SIP Garden Rooms

Create a properly insulated garden building that feels like part of your home rather than a seasonal outbuilding.

Garden rooms for work, exercise and everyday living

Our SIP garden rooms are individually designed around the available space, intended use, access, budget and desired finish. Structural insulated panels form a rigid, highly insulated envelope that is well suited to home offices, studios, gyms, cinema rooms, therapy rooms and multi-purpose family spaces.

Garden offices

Quiet, comfortable workspaces with space for desks, storage, data and heating.

Studios and creative rooms

Flexible layouts for art, music, photography, hobbies or client-facing work.

Gyms and wellness spaces

Robust, thermally efficient rooms designed around equipment, ventilation and privacy.

Bespoke leisure rooms

Bars, games rooms, cinema spaces and family rooms tailored to your garden.

What our service can include

Depending on your package, we can provide concept design, planning advice, Building Regulations information, structural engineering, foundation coordination, SIP manufacture, shell installation, roofing, windows, doors, cladding and internal completion.

Planning note: Some garden rooms may fall within permitted development, but use, height, position, land designation and sleeping accommodation can change the requirements. We assess this during the early design stage.
